Large number of
small antennas has sensitivity comparable to a
|
|
|
moderate sized
antenna. (Calibrator sensitivity ~
n * A)
|
|
|
| • |
Wide bandwidth
(Calibrator sensitivity ~ ÖBW)
|
|
|

Even with large
antennas, must rely heavily on self-calibration to achieve
|
|
|
dynamic range
goals.

Will almost
always have compact solar sources in FOV

|
|

Frequency-dependence
of phase variations with time can be simply
|
|
|
|
parameterized
(eg terms that scale with f and
f^-2.)
|
|
|
| • |
Lots of time
available for daily pre- and post-observation calibration
|
|
|
| • |
Frequency
coverage suggests that communications satellites might be
|
|
|
|
useful as
secondary calibrators.
